NK is a failed state led by a crazy man.
While the future of Korea is extremely important, the summit itself isn't. If Kim Jong-un wants to use the summit as a stage for political theatrics, then Trump is right to avoid it.
The one shining light in the Korean problem is that if Korea unifies without violence, Koreans and the world would get another reminder of how horrible Communism is for the people.
So, I don't care if the summit takes place but I hope the world leaders have their eyes on a peaceful resolve to the Korean stand off.
